A woman's nail separation was likely caused by poor blood flow, and a treatment for similar conditions might help.

This paper discusses the use of Digital Volumetric Imaging with fluorescent dyes to visualize and compare the interior structures of six different virgin hair types, reporting no new clinical results.

A new method helps understand hair shine and various products improve hair care.

The study suggests that CO₂ laser creates hair transplant channels with significantly less lateral thermal damage than Ho:YAG laser in the human scalp.

Hair treatments like bleaching increase friction by exposing tiny pores on the hair surface.

This review highlights pigment epithelium-derived factor's roles in ageing and development, focusing on its antioxidant functions and support of stem cell survival, but reports no new experimental results.

This study utilized advanced imaging techniques to quantify hair damage and dye uptake dynamics, revealing that compound penetration in hair is influenced by molecule size and lipophilicity.

Skin aging reflects overall body aging and can indicate internal health conditions.

This research studied European human hair, finding that cysteic acid and protein carbonylation increased with both chemical and photochemical oxidation. Protein carbonylation was highlighted as a more sensitive marker for photochemical oxidation, providing better in situ visualization of hair damage than cysteic acid.

This article reviews the biology of epithelial stem cells and their role in tissue self-renewal, maintenance, and regeneration, and it highlights the clinical implications of understanding their signaling pathways, but it presents no new clinical findings.

This article reviews the clinical complications and increased mortality risks associated with Cushing's syndrome but does not present new clinical data; it emphasizes the need for prompt treatment to mitigate these risks.

This review discusses the links between particulate matter exposure and skin diseases, highlighting oxidative stress and inflammation as key mechanisms; it reports no new clinical results.

This research found that Foxc1 transcription factor and COL17A1 are critical in regulating quiescence and hair thinning in hair follicle stem cells, with aging-related DNA damage leading to hair loss.

This article discusses the potential role of melatonin in protecting skin against stress and maintaining homeostasis, based on its local synthesis and various protective functions, but presents no new clinical results.

This review discusses gender-linked skin differences, such as hormone metabolism and sebum production, and reports no new findings; it suggests these insights might inform male-specific dermatological treatments or cosmetic products.

This review discusses the effects of visible light on human skin, highlighting its role in pigmentation, thermal damage, and the treatment of several skin conditions, while noting limited sunscreen protection against it; no new clinical results are reported.

This study found that both genetic and environmental factors influence appearance-related aging in women, with skin wrinkling, hair graying, and sun damage significantly affecting perceived age more than chronological age.

This review explores the impact of vitamin D deficiency on the skin from a dermatological perspective, but reports no new clinical results.

This review discusses the effects of estrogen on skin and reports no new clinical results; it highlights estrogen's potential benefits on skin thickness, collagen quality, and hair follicle life cycle.

This study found that delivering math1 via an adenovector led to vestibular hair cell regeneration and improved balance function in ototoxin-treated adult mice.

This review discusses the role of the circadian clock in skin functions such as cell proliferation and UV protection and reports no new results; the authors note its potential in studying immune regulation and seasonal behaviors.

This review discusses the potential role of oxidative stress in hair graying and age-related alopecia, emphasizing the need for new strategies to counteract these effects, but reports no new results.

This review examines apoptotic and anti-apoptotic mechanisms in skin homeostasis and related diseases but presents no new research findings.

This review discusses the potential of ultraviolet (UV) radiation technologies in wound care, highlighting their antimicrobial properties and risks of DNA damage, but reports no new clinical findings.

This review reports on the dual aspect of fullerene in skincare, highlighting its beneficial antioxidant properties as well as potential toxicity and skin cell reactions, while identifying areas for future research.

This study found that chronic ultraviolet-B exposure increased skin vascularization and wrinkle formation in mice, while overexpressing the angiogenesis inhibitor thrombospondin-1 reduced these effects, suggesting angiogenesis inhibition as a potential approach to prevent photo-damage.

This study found that the transcription factor FOXO1 plays a crucial role in wound healing by protecting keratinocytes from oxidative stress and regulating TGF-β expression.

This study found that deleting the miRNA processing enzymes Drosha and Dicer from mouse skin epithelial cells disrupted normal hair follicle development and maintenance, leading to follicular degradation and stem cell loss during the growth phase.

This article reviews central centrifugal cicatricial alopecia in African-descent females, discussing possible causes, associated styling habits, and potential treatments, but reports no new clinical findings; the authors call for further research.

This study suggests that dermal adipocytes might play a key role in skin aging due to their transformation into fibrotic structures in chronically photo-damaged skin.
